Vision Vision The topics in this chapter briefly describe the vision features in the ACE software, such as vision calibrations and vision programs. For detailed information on the vision features, see the ACE Sight User's Guide . Vision Overview 301 Vision Overview A vision system consists of some means of obtaining an image, and some means of pro- cessing that image. l ACE Sight systems typically uses one or more cameras to capture images for pro- cessing. These images can be stored for later processing, if desired. l Images are processed with ACE Sight vision tools. See Vision Tools on page 345. This topic introduces some of the concepts and terms used in the other vision topics.
If you're new to vision guidance/inspection, you should read the section on Vision Basics, starting with Vision Basics - Resolution on page 303 . Vision Devices A vision device can be either a physical camera or an emulated camera. Vision devices are added to the workspace as needed. You can have multiple vision devices in the workspace. See Vision Devices on page 315 . Physical Camera ACE Sight supports the following physical cameras: l Basler 1394a l Basler 1394b l Basler GigE l Basler Line Scan A physical camera needs to be calibrated, to establish the relationship between phys- ical distance in the camera's field of view and the pixels returned from the camera.
This type of calibration also helps correct for a certain amount of distortion in the lens. This calibration is covered in the section Standalone Camera Calibration on page 320 . If the camera will be used with a robot and/or conveyor belt, the camera also needs to be calibrated with respect to those devices. Those are separate calibrations, distinct from the relatively simple distance-pixel calibration. These calibrations are added as objects in the workspace.
